Panel Features
2.1 Description
The DMP XR150/XR350/XR550 Series system is made up of an alarm panel with a built-in communicator, an enclosure,
battery, one transformer, and keypads. Each panel is a versatile 12 Vdc, combined access control, burglary, and re
communicator panel with battery backup. The panels provide eight on-board burglary zones and two on-board 12 Vdc
Class B powered zones. The powered zones have a reset capability to provide for 2-wire smoke detectors, relays, or other
latching devices. Combined current requirements of additional modules may require an auxiliary power supply. Refer to
the Power Requirements section in this guide when calculating power requirements. The panels can communicate to DMP
SCS-1R Receivers using digital dialer, cellular, network, or Contact ID communication. Panels using cellular, network, or
encrypted communication can also communicate to DMP SCS-VR Receivers.
2.2 Zone Expansion
Each panel provides multiple options for zone expansion:
• 10 on-board zones
• Up to 64 programmable keypad zones
• Up to 500 LX-Bus zones
Using DMP LCD keypad remote zone capability and zone expansion modules, additional zones are available on each panel:
• XR550 provides up to 574 additional zones
• XR350 provides up to 374 additional zones
• XR150 provides up to 142 additional zones
The panel keypad data bus supports up to 16 supervised device addresses with each address supporting up to four
programmable expansion zones (64 total).
Using the on board LX-Bus™ connections, and any combination of single, four, eight, or sixteen-zone expansion modules
and single-zone LX-Bus™ detectors, additional zones are available on each panel:
• XR550 provides up to 500 additional zones (LX500-LX900)
• XR350 provides up to 300 additional zones (LX500-LX700)
• XR150 provides up to 100 additional zones (LX500)
Note: Do not use shielded or twisted pair wiring for LX-Bus or Keypad Bus circuits.
2.3 Output Expansion
In addition to the two SPDT relays and four programmable open collector outputs on the XR150/XR350/XR550 Series, you
can also connect up to 25 programmable Model 716 Output Expansion Modules to each LX-Bus. These modules can provide
an additional 500, 300, or 100 programmable SPDT relays.
The panels provide Output Schedules for programming the 716 to perform a variety of annunciation and control functions.
Also assign the 716 outputs to any panel Output Options such as Fire Alarm, Communication Fail, or Phone Trouble Outputs.
Refer to the 716 Installation Guide (LT-0183).
The LX-Bus™ also supports the Model 717 Graphic Annunciator Module. Each 717 module supplies 20 switched ground
outputs that follow the state of their assigned zones.
Note: The 717 supports the rst eight Keypad Bus addresses. To follow Keypad Bus addresses nine through 16, install
multiple 716 modules. Refer to the 717 Installation Guide (LT-0235) and 716 Installation Guide (LT-0183).
2.4 Central Station Communication
You can program the panel for reporting to DMP SCS-VR or SCS-1R Receivers using digital dialer, cellular, network, or
Contact ID communication. The panels connect at the premises to a standard RJ31X or RJ38X telephone jack. Use the DMP
893A Dual Phone Line Module when connecting the panel to two separate phone lines in re or burglary applications.
2.5 Encrypted Communications (XR550 with Network & Encryption Only)
An XR550 panel can communicate using AES encryption. If you currently have an XR550 panel with network capability, you
may contact DMP Customer Service with the panel serial number. The serial number(s) should be sent in writing via e-mail
or fax. A separate feature key is sent for each panel to activate encrypted communications using the Feature Upgrade
process. Encrypted communication cannot be enabled on a XR550 panel without network communication capabilities. For
more information on the Feature Upgrade process see the XR150/XR350/XR550 Series Programming Guide (LT-1232).
Note: 256-bit encrypted messages to SCS-1R receiver only communicate when using SCS-104 Receiver Line Cards
with Version 102 or higher software.
2.6 Caution Notes
Throughout this guide you will see caution notes containing information you need to know when installing the panel. These
cautions are indicated with a yield sign. Whenever you see a caution note, make sure you completely read and understand
its information. Failing to follow the caution note can cause damage to the equipment or improper operation of one or
more components in the system. See the example shown below.
Always ground the panel before applying power to any devices: The panel must be properly grounded
before connecting any devices or applying power to the panel. Proper grounding protects against Electrostatic
Discharge (ESD) that can damage system components.
2.7 Compliance Instructions
For applications that must conform to a local authorities installation standard or a National Recognized Testing Laboratory
certicated system, please see the Compliance Listing Guide LT-1330 for additional instructions.
